India will send a new Earth observation satellite to space tonight (Aug. 11) to keep an eye on natural disasters, agriculture and forestry regions.

The India Space Research Organisation (ISRO) is scheduled to launch a Geosynchronous Satellite Launch Vehicle (GSLV) carrying the the EOS-03 satellite from the Satish Dhawan Space Centre in eastern India, near the Bay of Bengal, at 8:43 p.m. EDT  (0043 GMT or 5:43 a.m. local time Friday, Aug. 12.) You can watch the launch live on this page, as well as on the ISRO website and YouTube channel at liftoff time. The webcast will begin at 7:40 p.m. EDT (2343 GMT). 

The GSLV rocket is expected to place the satellite into a preliminary transfer orbit, and EOS-03 is expected to boost itself to geosynchronous orbit in the following days.

ISRO officials describe EOS-03 as a “state-of-the-art” Earth observation satellite with three main objectives: near real-time imaging with frequent revisits to the same region, monitoring natural disasters and other short-term events, and picking up spectral signatures for agriculture and forestry to monitor items like crop health.

Wednesday’s launch will be the fourteenth for the GSLV rocket type, which Indian news sources best remember as the launch vehicle for Chandrayaan-2, India’s second lunar exploration mission that launched successfully from the same center in July 2019. While the combination lander-rover crashed during a landing attempt, the orbiter is still working well as it continues the search for lunar ice.

EOS-03 was delayed due to the ongoing coronavirus pandemic, which forced engineers and scientists to work remotely, according to an India Today report. ISRO is trying to recover its footing and to launch more frequently in the coming months, the report added, with EOS-04 expected to launch in September. The September mission will include synthetic aperture radar to peer through clouds, and will launch aboard a Polar Satellite Launch Vehicle (PSLV).

EOS-03 will be ISRO’s first satellite launch since Dec. 17, 2020 when the CMS-01 communications satellite went to space, according to agency data. ISRO completed three launches in 2020 in January, November and December; the pandemic erupted that March.

ISRO also plans to launch a three-stage solid rocket called the Small Satellite Launch Vehicle (SSLV) by the end of 2021, India Today noted. The SSLV will be able to launch payloads to polar orbit or to sun-synchronous polar orbit (meaning that any satellite would have consistent lighting conditions below.)

Along with launching EOS-03, the GSLV will mark its first flight with a 13-foot (4-meter) payload fairing on board. The fairing will allow the rocket to accommodate larger payloads, ISRO stated.
